Butterfly-Valve-Flange-Type-WLD-D343H
¡¾Uses¡¿
Three eccentricity metal hard sealing butterfly valve with three-dimensional structure of the eccentric multi-level metal seal for medium temperature ¡Ü 600 ℃ metallurgical, power, petrochemical, air, gas, combustible gas, and water supply and drainage pipes and other media to do adjust the flow and stage fluid devices.
¡¾Three eccentricity metal butterfly valve seal sealing principle¡¿
Three eccentric butterfly valve with bi-directional bubble tight shut-free performance. The geometry of the valve seal is only guaranteed in the closed position when the contacts with the valve seat, so no friction or wear, and produces a torque makes the elastic sealing has enough "welding" properties, to ensure the consistency of sealing contact.
Triple Offset¡¿ ¡¾geometry
Eccentric shaft of a valve shaft in the back seat, the seal around the contacts to completely close the valve seat.
Deviation from the centerline of the eccentric shaft, two valves centerline of pipes and valves, which open and close the valve from the interference.
Eccentric cone axis deviation from the three valve of the valve shaft centerline, so that in the process of closing and opening to eliminate friction and to achieve uniform around the entire seat of the compression seal.
¡¾Frictionless seal for longer life¡¿
(1) as a standard configuration, valve seat with Cr13 alloy Stellite hardfacing.
(2) The use of spiral wound gasket of stainless steel / graphite, used to achieve zero leakage.
(3) Close the valve seat during the torque generated by force, and the role of uniform around the entire circumference. Elastic bending and dynamic seal to maintain the shape of the valve seat. Compressive force evenly along the perimeter effect, allows the valve to two-way flexibility makes close off the valve seal and valve body to contact or expansion, to avoid the temperature fluctuation of the risk of clogging. This device is able to adjust alignment.
